摘要： An optical fiber rotary measurement sensor for flow meters and other mechanical devices incorporates a housing having an encoder disc mounted by a drive shaft for driven rotation, the drive shaft being driven by a flow meter mechanism or by any other mechanical device. The encoder forms evenly spaced light absorbing and light reflecting areas at the outer periphery thereof and optical fibers are positioned to project light onto and receive reflected light from the outer periphery of the encoder disc. An opto-electronic signal processor receives reflected light pulses from the reflective surface areas and translates the light pulses into electrical pulses. The electrical pulses are in turn input to electronic display circuitry for providing a digital, analog or other suitable display representative of the rotation of the encoder disc and thus representative of rotary output movement of the flow meter or other mechanical device.
